For some reason it does not let me post in the main forum maybe its because I am a new member.

It is possilbe to add a date element or something to choose a date in the application settings? I can't find something in the documentation from apple.

Thanks in advance

As for as I know I have covered the exhaustive list of tools available in Settings Bundle. Sorry. For the date I guess your best option is a combination of multivalue specifiers.

Sorry could not be of more help

Does any of you guys know how to do the gray text that appears in an empty field? Like "Required" or "Ask Every Time" for a password? At first i thought it was what "DefaultValue" was for, but i guess not..

How can i make, that the settings is in the app itself and not in the settings "app"

you must design a view and define costant value that you've create in your plist

#define kUnit			@"unit"
#define kGps			@"gps"

and after read your preference in viewDidLoad or similar in this way (simulating a slider and on/off button)

	NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
	onoff.on = [defaults boolForKey:kUnit];
	sliders.value = [defaults floatForKey:kGps];

and after you must save your data in viewWillDisappear or similar method:

[super viewWillDisappear:animated];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:onoff.on forKey:kUnit]; 
[defaults setFloat:gps.value forKey:kGps];
[defaults synchronize];

In the view you need that settings you must read each time viewWillAppear

	NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
	onoff.on = [defaults boolForKey:kUnit];
	sliders.value = [defaults floatForKey:kGps];

hope helps!
